I have mine in the centre, but I doubt that it will make much difference because the exhaust gas flow will be quite turbulent just after the turbo

put it in all the way, the more probe exposed = more accurate reading imho

they measure the temp where the thermocouple junction is which is the very tip of the probe. put it halfway in.

Contact the company and ask them.

It does make a difference.

The sensitive part of the probe is only about 5mm from the tip. Normally we place them into the exhaust between 5 and 15mm, depending on the size of the exhaust pipe. Any further in and you will be creating unnecessary turbulence in the exhaust system.
Google EGT Probe Length and you’ll get the answer.
